BENCH-=VISE.

SPECIFICATION formingpart of Letters Patent No. 680,439, dated August13, 1901. Application filed February 16, 1901. Serial No. 47,657. (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY F. RENNER, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Bench-Vises and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the'same, reference being had to theaccompanying drawings,and to the letters of reference marked thereon,forming part of this specification.

My invention relates to bench-Vises, and particularly to that typehaving an adjustable jaw, so as to adapt the vise to clamp both straightand tapering pieces.

The principal object of my invention is to simplify and improve themanner 'of mounting the adjustable jaw upon and connecting it with thevise-frame. To accomplish this result, I make a circular flanged openingin the top of the vise-frame, having parts of the flange cut away, andupon the under surface of the adjustable jaw there is adownwardlyprojecting stud havinga flange partly broken away on its lowerend adapted to interlock with the flange in the opening in the framewhen the adjustable jaw is in operative position, rendering the jawcapable of being easily adjusted, while at the same time it isexceedingly stable in its connection with the vise-frame.

The features of this invention are hereinafter set forth and described,and illustrated in the accompanying drawings, in which Figure l is alongitudinal section of a vise embodying my invention. Fig. 2 is a topor plan view of the vise with the adjustable jaw removed, but with itshown in dotted lines in place thereon. Fig. 3 is a View of the undersurface of the adjustable jaw shown in dotted lines in Fig. 2.

In the drawings thus illustrating my invention, A is a vise-frame, B thelongitudinallymoving jaw thereof, 0 the screw for operating thelongitudinally-moving jaw, and D the nut secured in the frame A, all ofwhich parts, except the frame A, are of the usual construction.

The frame A is provided with a plain horizontal surface or j aw-seat aabove the opening A, in which the arm 13 of the jaw B opcrates, and inthe horizontal surface aof the frame, near the front end thereof, thereis a -circular opening E, which preferably extends down into the openingA. Around the upper edge of the opening E there is aninwardly-projecting flange e, having portions thereof cut away at e ande on the opposite sides thereof, said opening and the flange thereinbeing clearly shown in Figs. 1 and 2. There is also an opening a in theupper surface ct of the frame, near the rear end thereof, as and for thepurpose hereinafter set forth. Upon the surface a of the frame A, I

place an adjustable jaw F, Fig. 3. The under face of this jaw F isprovided with a stud F, which projects downward from the under surfaceof the jawFand is provided with sections f f of an annular flange aroundthe lower end thereof, the sections f f of the flange thereon beingadapted to pass down through the openings e a m the flange e in theopening E in the frame when the jaw F is at right angles to the frame A,and on being turned slightly the flange-sections ff interlock with theflange-sections c e on the frame,

as illustrated in Fig. l, and prevent the jaw v F from being lifted up,yet allow the jaw to swing freely in the opening E in the frame and beused. at any angle to the jaw B- desired.

Through the adjustable jaw F, I make a hole f which is adapted toregister with the hole a in the frame when the faces of the jaws B and Fare parallel and receive a pin I, placed in said holes to retain the jawin such position.

Having thus fully described my invention, its operation is so obvious asto enable others to use the same without further description thereof.Therefore what I claim as new, and desire to secure by Letters Patent ofthe United States, is-

1. The combination in a bench-vise of a frame, a seat for an adjustablejaw thereon having a circular opening therein, an interrupted annularflange around said opening, an adjustable jaw fitting upon said seat, astud thereon projecting down into the flanged opening therein, and aninterrupted annular flange on said stud, adapted to engage the havingspaces of unequal length thereon interrupted flange in said opening,substan adapted'to engage the flange-sections in said tially as and forthe purpose set forth. opening, substantially as and forthe purpose 2.lhe combination in a benoh-vise, of a set forth.
